After reading all of these comments and questions, I still want to ask mine. I feel dumb, but I want to get educated. I like my truck running the way it is. Good! My IQUAD adapter came in. I’ve been running the control pod for the last year. I have a 1999, 4x4 automatic. Cold air intake, air dog 150, and a turbo elbow Orifice. I a, new to this custom tuning, and I really don’t want to mess up anything. I don’t how this all works, espically changing the timing. This is my Daily Driver. If y’all could give me some tunes to start with, that would be greatly appreciated.
